Beschreibung
Zusammenfassung:	A secondary battery includes a cathode; an anode (1) including a plurality of carbon particles and a plurality of non-carbon particles, (2) the carbon particles containing graphite, (3) the non-carbon particles containing a material including, as a constituent element, one or more of silicon (Si), tin (Sn), and germanium (Ge), and (4) a distribution of a first-order differential value of an integrated value Q of a relative particle amount with respect to a particle diameter D of the plurality of carbon particles having one or more discontinuities, where a horizontal axis and a vertical axis of the distribution indicate the particle diameter D (μm) and a first-order differential value dQ/dD, respectively; and an electrolyte.
